非線形モデルを用いた大型連結貨物車両の曲線路走行時の挙動と横転危険性の評価検討

This paper deals with response behavior and rollover resistance of heavy duty truck in cornering. We focus on the connection type vehicle that consists of one tractor and one trailer. The vehicle is expressed by 7 nonlinear equations of motion and 2 constraint conditions of connecting point. The equations include the nonlinear property of the tire lateral force. We use the rate of decrease of wheel load as the index for judging rollover. We perform parameter study about the eccentric distance of center of gravity, the running speed and so on, and investigate the degree of the risk of rollover.
